Included in this archive is all of the java byte-code required to run the simulator. I've also included all source code. You can run the simulator interactively from the command line with a 'java Parrondo' command: the simulator will generate a text file with the numeric results. You can run the graphic interface by launching the ParrondoApplet.html file in a java-enabled browser or applet viewer, but note the Netscape related problems described in problems.txt. Thanks for trying this out! I appreciate any feedback. Asher Langton jlangton@sandiego.edu 19 January 2001 (10/12/02) I updated the ParrondoApplet.java file to fix a synchronization issue. (12/13/04) Changed DataOutputStream to PrintWriter, and recompiled with a newer compiler, so it will work with newer JVMs. Also, if you get an error like Exception in thread "main" java.lang.UnsupportedClassVersionError: Parrondo (Unsupported major.minor version 49.0) at java.lang.ClassLoader.defineClass0(Native Method)... it's probably because your Java Virtual Machine is newer than the one I was using when I compiled it. This easiest fix (if you have a java compiler installed) is to delete the .class files and recompile the 3 java files. --Asher Langton
